SpringMVC整合ElasticSearch

SpringMVC整合ElasticSearch步骤如下：

在maven引入Elastic jar包，在pom.xml中添加如下内容：

<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>6.2.2</version>
</dependency>
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-client</artifactId>
<version>6.2.2</version>
</dependency>
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>6.2.2</version>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-elasticsearch</artifactId>
<version>3.1.3.RELEASE</version>
</dependency>

在applicationContext.xml文件中引入spring-elastic.xml

<import resource="spring-elastic.xml"/>

创建spring-elastic.xml文件，配置文件内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:elasticsearch="http://www.springframework.org/schema/data/elasticsearch"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/data/elasticsearch
http://www.springframework.org/schema/data/elasticsearch/spring-elasticsearch.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">

<context:component-scan base-package="com.elastic" />


<elasticsearch:repositories base-package="com.climber.elastic.repository" />


<elasticsearch:transport-client id="client" cluster-nodes="192.168.0.116:9300"/>


<bean id="elasticsearchTemplate"
class="org.springframework.data.elasticsearch.core.ElasticsearchTemplate">
<constructor-arg name="client" ref="client" />
</bean>
</beans>

创建Bean

创建Stu，具体代码如下：

package com.climber.elastic;

import java.io.Serializable;
import java.util.Date;

import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;
import org.springframework.data.elasticsearch.annotations.Field;
import org.springframework.data.elasticsearch.annotations.FieldType;

/**
* index：是否设置索引， store是否存储数据，type:数据类型，analyzer：分词粒度选择，searchAnalyzer：查询进行分词处理
* ik_smart：进行最小粒度分词，ik_max_word进行最大粒度分词
* @author Derlin
*
*/
@Document(indexName = "stu", type = "doc")
public class Stu implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@Field(index=true, store = true, type = FieldType.Long)
private Long id;

@Field(index = true, analyzer = "ik_max_word", store = true, searchAnalyzer = "ik_smart", type = FieldType.Text)
private String stuId;

@Field(index = true, analyzer = "ik_max_word", store = true, searchAnalyzer = "ik_smart", type = FieldType.Text)
private String stuName;

@Field(index = true, store = true, type = FieldType.Date)
private Date createTime;

@Field(index = true, analyzer = "ik_max_word", store = true, searchAnalyzer = "ik_smart", type = FieldType.Text)
private String sex;

public Stu() {
}

public Stu(Long id, String stuId, String stuName, Date createTime) {
this.id = id;
this.stuId = stuId;
this.stuName = stuName;
this.createTime = createTime;
}

public Long getId() {
return id;
}

public void setId(Long id) {
this.id = id;
}

public String getStuId() {
return stuId;
}

public void setStuId(String stuId) {
this.stuId = stuId;
}

public String getStuName() {
return stuName;
}

public void setStuName(String stuName) {
this.stuName = stuName;
}

public Date getCreateTime() {
return createTime;
}

public void setCreateTime(Date createTime) {
this.createTime = createTime;
}

}

通过Repository进行CURD，定义Repository如下

@Repository
public interface StudentRepository extends ElasticsearchRepository<Stu, Long> {

/**
* @param stuId
* @return
*/
Stu getByStuId(String stuId);

/**
* @param stuName
* @return
*/
List<Stu> getListByStuName(String stuName);

/**
* @param stuName
* @param pageable
* @return
*/
Page<Stu> getPageByStuName(String stuName, Pageable pageable);

}

在Service层定义接口

public interface EsService {

public void createDocument(Stu stu);

public Stu getByStuId(String stuId);
}

定义接口实现

@Service("esService ")
public class EsServiceImp implements EsService {

@Resource
private StudentRepository studentRepository;

@Override
public void createDocument(Stu stu) {
studentRepository.save(stu);
}

@Override
public Stu getByStuId(String stuId) {
return studentRepository.getByStuId(stuId);
}

}

Controller调用如下

@Controller
@RequestMapping("/es")
public class EsController {

@Resource
private EsService esService;

@RequestMapping("/elastic")
public void elastic(){
Stu st = new Stu(6L, "006", "小陈", new Date());
esService.createDocument(st);
Stu stu = esService.getByStuId("006");
System.out.println(stu.getStuName());
}

}

执行http://localhost:8080/elastic/es/elastic.do后，用浏览器输入http://192.168.0.116:9200/stu/_search?q=*&pretty即可查看数据已保存到Elastic
